[0002] A transport rack anti-collision mechanism is typically used in automobiles, mechanical equipment or other facilities to reduce damage caused by collision or impact. In industrial environments, robots, lifting equipment and other large machinery may be equipped with a transport rack anti-collision mechanism to prevent them from accidentally colliding during operation, thereby protecting workers and equipment.

[0003] After searching, the publication number CN215891628U discloses a transport rack anti-collision mechanism, including a sliding cover plate, a first pin shaft, a second pin shaft and a fixed seat, the sliding cover plate includes a first sliding plate, a second sliding plate and an anti-collision plate, the anti-collision plate has a first side wall and a second side wall, the first sliding plate and the second sliding plate are arranged on the first side wall of the anti-collision plate, the second side wall of the anti-collision plate is provided with a first protrusion, a first groove, a second protrusion and a second groove, the first protrusion, the first groove, the second protrusion and the second groove are connected in sequence to form a rectangle, and the first protrusion is adapted to the second groove, and the second protrusion is adapted to the first groove. When two display screens are spliced, the two sliding cover plates are first abutted, and then the sliding cover plates slide, so that the side walls of the two display screens are abutted, so as to buffer the collision and avoid damage to the LED lamp body, and solve the problem that the LED lamp body may be damaged due to the collision caused by the splicing of the two display screens.

[0037] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0038] Reference Figure 1-Figure 3 , an embodiment provided by the utility model: a transport rack anti-collision mechanism, including a base 1, a connecting column 2 is arranged inside the base 1, an anti-collision head 3 is arranged on one side of the connecting column 2, a threaded rod 4 is fixedly connected inside the anti-collision head 3, the outer wall of the threaded rod 4 is threadedly connected to the inside of the connecting column 2, and a nut 5 is threadedly connected to the outer wall of the threaded rod 4, a card slot 6 is provided inside the connecting column 2, a limiting groove 7 is provided inside the nut 5, a limiting plate 9 is arranged inside the nut 5, the outer wall of the limiting plate 9 is slidably connected to the inside of the limiting groove 7, a conical column 8 is fixedly connected on one side of the limiting plate 9, the outer wall of the conical column 8 is embedded in the card slot 6, a reset component is arranged inside the nut 5, a telescopic rod 10 is arranged inside the nut 5, one end of the telescopic rod 10 is fixedly connected to the inside of the nut 5, and the other end of the telescopic rod 10 is fixedly connected to the other side of the limiting plate 9, the reset component includes a first spring 11, the first spring 11 is sleeved inside the outer wall of the telescopic rod 10, one end of the first spring 11 is fixedly connected to the other side of the limiting plate 9, and the other end of the first spring 11 is fixedly connected to the inside of the nut 5;

[0039] Specifically, when the extension length of the anti-collision head 3 needs to be adjusted, the following steps can be followed. First, gently rotate the anti-collision head 3 so that it and the threaded rod 4 produce relative movement. The key to this step is to ensure that the threaded rod 4 can be smoothly rotated out from the inside of the connecting column 2. During the rotation process, it is necessary to pay attention to the operating force to avoid excessive or insufficient force causing damage to the equipment or inaccurate adjustment. Next, tighten the nut 5 in the direction of the connecting column 2. The purpose of this step is to fix the position of the threaded rod 4 and the anti-collision head 3 for subsequent adjustments. In the process of tightening the nut 5, it is also necessary to pay attention to the operating force to ensure that the nut 5 is tightly combined with the connecting column 2, but not too tight to cause damage. Then, the conical column 8 in the nut 5 is embedded in the slot 6. This step is the key to the entire adjustment process. The degree of embedding of the conical column 8 will directly affect the extension length of the anti-collision head 3. In order to ensure that the conical column 8 can be smoothly embedded in the slot 6, the conical column 8 and the slot 6 can be cleaned before operation to remove possible impurities or dirt. The conical column 8 is limited in position in the nut 5 by the limiting plate 9, and this design can effectively prevent the conical column 8 from deflecting or tilting during the fitting process, thereby ensuring the accuracy and stability of the fitting. At the same time, the limiting plate 9 can also play a certain supporting role for the conical column 8, making it more stable during the fitting process.

[0040] Reference Figure 1 and Figure 4 , one end of the connecting column 2 is fixedly connected with a connecting pin 13, a positioning groove 12 is opened inside the base 1, a limiting column 14 is fixedly connected inside the connecting pin 13, the outer wall of the limiting column 14 is slidably connected with a limiting ring 15 which is symmetrically arranged, the outer wall of the limiting ring 15 is rotatably connected with a connecting rod 16, one end of the connecting rod 16 is rotatably connected with a clamping block 17, the outer wall of the clamping block 17 is embedded in the positioning groove 12, the outer wall of the connecting pin 13 is slidably connected to the inside of the base 1, and the outer wall of the limiting column 14 is sleeved with a second spring 18, one end of the second spring 18 is fixedly connected to one end of the limiting ring 15, and the other end of the second spring 18 is fixedly connected to the inside of the connecting pin 13;

[0041] Specifically, first, the anti-collision head 3 is inserted into the base 1 through the connecting pin 13 at one end of the connecting column 2. The design of the connecting pin 13 must ensure that it can be tightly inserted into the corresponding hole of the base 1, and at the same time, the friction and stability between the connecting pin 13 and the base 1 must be ensured. Next, the block 17 in the connecting pin 13 will be embedded in the positioning groove 12. This process involves the precise matching of the block 17 and the positioning groove 12. The design of the block 17 must be able to be tightly embedded in the positioning groove 12 to ensure that the anti-collision head 3 can be stably fixed on the base 1 when it is impacted by external force to prevent accidents. In order to ensure the stability and reliability of the block 17, the block 17 is limited on the limiting column 14 by the connecting rod 16 and the limiting ring 15. This design can effectively prevent the block 17 from falling off or shifting when subjected to external force, thereby ensuring the stability and reliability of the connection between the anti-collision head 3 and the base 1. In addition, by supporting the limiting ring 15 with the tension of the second spring 18, not only the stability of the limiting ring 15 can be enhanced, but also the impact of external force on the anti-collision head 3 can be alleviated to a certain extent. This design can not only protect the anti-collision head 3 from damage, but also reduce the pressure and impact force on the base 1. In actual operation, if the position of the anti-collision head 3 needs to be replaced or adjusted, it is only necessary to push the limiting ring 15, thereby driving the connecting rod 16 to support the block 17, so that the anti-collision head 3 can be easily disassembled and reinstalled. This design not only facilitates the use of operators, but also improves the maintainability and flexibility of the equipment.

[0042] Working principle: When using this kind of transport rack anti-collision mechanism, when it is necessary to add the anti-collision head 3, it is only necessary to insert the anti-collision head 3 into the base 1 through the connecting pin 13 at one end of the connecting column 2, and then the block 17 in the connecting pin 13 is back-engaged in the positioning groove 12, and the block 17 is limited on the limit column 14 through the connecting rod 16 and the limit ring 15, and the limit ring 15 is supported by the tension of the second spring 18, and then the limit ring 15 is pushed to drive the connecting rod 16 to support the block 17. When it is necessary to adjust the extension length of the anti-collision head 3, it is only necessary to rotate the anti-collision head 3 through the threaded rod 4 to turn the threaded rod 4 out of the inside of the connecting column 2, and then tighten the nut 5 in the direction of the connecting column 2, and then make the conical column 8 in the nut 5 engage in the inside of the card slot 6, and the conical column 8 is limited in the nut 5 by the limit plate 9. The conical column 8 is supported by the tension of the first spring 11, so that the conical column 8 is embedded in the card slot 6 and is not easy to slide out, thereby fixing the nut 5.
